Firework Help

Im playing in to tutorial world right now and noticed the fireworks that pop up when you cross over the wire. Can the recipes for the four that pop be found online? I want to add more so they don't run out.

I wondered about this also, a creeper kinda ruined part of that area where the tripwire is and I was trying to repair it and found a trail of redstone and then tried to follow it by digging around to see where the fireworks launch. I wish there was a map for this so I can fix it, lol+
